  • Device for controlling vehicle equipped with multi-stage automatic transmission
    Patent number: 11046324
    Abstract: A control device for a multi-stage automatic transmission-equipped vehicle includes a hydraulic power controller, a combustion controller configured to, if a predetermined combustion stop condition is satisfied when the vehicle is traveling, perform deceleration-period combustion stop control, and limit combustion restart triggered by a reduction in rotational speed of an internal combustion engine, during execution of the deceleration-period combustion stop control, and a motoring controller configured to control the rotational drive of the internal combustion engine by a motor during execution of the deceleration-period combustion stop control so that the rotational speed of the internal combustion engine is maintained at a predetermined rotational speed during a period of time from the time that the rotational speed of the internal combustion engine decreases to the predetermined rotational speed until downshifting to a predetermined gear ratio is completed.

  • Vehicle control apparatus
    Patent number: 10189475
    Abstract: Provided is a control apparatus of a vehicle, which includes a transmission mode switching control program for controlling the automatic transmission to switch between an automatic transmission mode and a manual transmission mode, a coast idle stop control program for performing a coast idle stop control in which the engine is stopped automatically and the automatic transmission is changed into a neutral position while the vehicle is traveling, and a coast idle control program for performing a coast idle control in which the engine is made running idle and the automatic transmission is changed into the neutral position while the vehicle is traveling.
